Circuit Solutions Adds Selective Wave Soldering Capability


Reading time ( words)

UK-based contract electronics manufacturer (CEM) Circuit Solutions Ltd (CSL) has invested in a new Ersa Versaflow 3/45 selective wave soldering machine.

Circuit Solutions provides contract manufacturing services to the higher technology end of the electronics industry, with increasing numbers of clients requiring IPC 610 Class 3 standards of soldering on assemblies with multilayer PCBs. The Ersa Versaflow 3/45 provides CSL with the capability to provide the minimum 75% barrel fill soldering required for IPC 610 Class 3—even on multilayer boards with heavy copper inner layers that would be impossible to achieve by conventional wave or hand soldering.

Paul Edmondson, CSL’s Manufacturing Engineering Manager, trialed a particularly challenging multilayer mixed technology assembly, with through-hole pins very close to previously fitted SMT components, over several different manufacturers machines before deciding on the Ersa product. Now several months on from the initial installation, Edmondson comments, "We have been extremely impressed with the capability of the Versaflow, and it has given Circuit Solutions the extra dimension we need to operate in a highly competitive market sector. In addition, the cosmetic appearance of the finished products is also much improved—which is important for a number of our clients."

CSL ordered a two solder-module version of the Versaflow proving them with the optimum mix of throughput, accuracy and flexibility, and are now looking to add a second selective wave soldering machine later in the year.

Investigation on the Assembly Process for m03015 and a Brief Look at m0201 Components

11/14/2018 | David Geiger, Robert Pennings, and Jane Feng, Flex
Components continue to shrink in the SMT world, and the next evolution of passive components includes m03015 (009005) and m0201 (008004). The m03015 and the m0201 components will see primary adoption in products that require further miniaturization, which would be SiPs. These modules would then be assembled into products through attachment, another assembly, or via other interconnect methods. This article explores the development of an assembly process (SMT only) for the m03015 component.

How to Avoid Common Wave Soldering Issues

11/13/2018 | Neil Blundell, Blundell Production Equipment
Wave soldering involves using waves of molten solder that act as glue to attach electrical components to the PCB. While this process is expedient and efficient in producing high-quality products, it sometimes experiences glitches that can be prevented or corrected. This article explores some of the main issues and how to remedy them.
